Subarus new Justy supermini is now on sale, offering outstanding fuel economy, equipment and space plus ultra-low exhaust emissions which should make it exempt from the proposed new London Congestion Charge.

In fact, with a 64.2 mpg Extra Urban figure, ultra-low 118 g/km exhaust emissions and annual ??35 Road Fund Licence, the new Justy 1.0 R promises to be one of the cheapest petrol-engined cars to run on UK roads.

However, the five-door body offers interior space from the next class up while the efficient, 69 PS three-cylinder 1.0 litre engine offers sufficient power for long-distance driving. Top speed, for example, is almost 100 mph and the 0-60 mph time is 13.5 seconds.

The new Subaru Justy also carries a peace-of-mind five-year/60,000 mile warranty backed by five-years UK and European roadside assistance.
